To all whom it may concer/n.'

Be it known that l, EDWIN E. BARNEY, citizen of the United States, and resident of New Rochelle, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a specilication.

My invention relates to typewriting ma@ chines, and more particularly to a small, compact, portable machine intended to be transported or carried in its carrying case, such a machine, for example, as the Remington Portable. l

ln portable machines it is desirable to contine the length of the platen as much as possible, consistent with the requirement for writing on paper of standard widths, and to accordingly confine. the length of the carriage in order not to exceed the necessary Widthwise dimensions .of the machine. One ditliculty, however, that presents itself 1n thus restricting the machine to taking paper of approximately standard widths, is that work sheets of greater widths, and more particularly standard large sized envelopes, cannot be introduced into the machine Without folding them, which is undesirable.

One object of my invention is to provide a construction which overcomes this diliiculty and enables comparatively wide work sheets, or standard large sized envelopes, to be introduced in unfolded condition into and .be properly ted through the machine, and in which it is unnecessary to increase the length of the platen or the carriage, to attain the results. k f

Another object of-my invention is to provide a novel construction and arrangement of parts. including a finger piece for turning the platen which may be moved from an expanded position for use to a compact position where it enables the machine to be enclosed within its carrying case.

ln the accompanying drawings, wherein like reference characters indicate corresponding parts in the different views,

Figure 1 is a detail fragmentary rear elevation. with parts in section and parts omitted. of a Remington Portable machine embodying my invention and conditioned for transportation within its carrying case.

Figure 5 is an end view of the carria e and associated parts as seen from the le t, and with parts in section. i

Fi ure 6 isa detail perspective view of the right-hand combined carriage end plate and off-set bracket arm.

l have shown my invention in the present instance embodied in a Remington Portable machine. but have illustrated only so much of said machine as is necessary to disclose my invention in its inclusion therein. The invention may be readily empio ed in such a machine without material mo ification of its existing structural features except by the substitution of parts, as will hereinafter more clearly appear. t should be understood. however, that the invention is not restricted to its employment in such machines.

The present invention has the same general ends in view as the construction disclosed in a companion application filed by me of even date herewith and bearing S1'. No. (il-2.235. ln said companion application claims are included which cover theconstruction disclosed herein, whereas the claims of the present application are specific to features not disclosed in said companionapplication.

ln the Remington Fortable machine, as at present marketed, and as disclosed in the application of Joseph B. Holden, Sr. No. 533,945, `tiled Feb. 3, 1922, a plate 8% inches long is employed, which enables a full written line to be produced on standard sized sheets; such sheets not exceedin 835 inches in width. However, said machines do not enable a large sized standard envelope of 9% inches to be used in the machine without -folding such envelope. By my present invention, a work sheet or envelope ci? inches in width maybe used without folding it, and without increasing the length of the platen or carria so that the machine may be received wit in the same carrying case that is new in use, and without eliminating any of the advantages which accrue to the said machine as it is now employed.

In the Remington Portable machine, a carriage support 8 is mounted at its rear end for fore-and-aft case shifting movement on parallel-arms 9. These arms are fixed on a rock shaft 10, pivoted at its reduced ends 11 in the frame 12 of the machine. The upper ends of the arms 9 are pivoted at 13 to lu 14 on the carriage support. The shiftabl support 8 carries a carriage comprising a main carriage bed 15 mounted in the usual manner on bearing rollers (includin rollers 16) to travel along the support 8. he carriage and associated partsremain substantially as they formerly were except at the right-hand end of the carriage. At this end the usual carriage end plate has substituted therefor a member, preferably formed as a combined end plate and bracket arm. This member is designated as a whole by the reference numeral 17, and is shown -the work sheet a is adapted to detached and in detail in Fig. 6. The member 17 is preferably made of sheet metal and comprises a foot piece `y18 secured by screws 19 to the carriage bed 15. Projecting upwardly from this foot piece is a carriage end plate 20, preferably formed as shown, with all parts thereof arranged outside of lines coincident with the cylindrical surface of the platen.y This is in order that the end plate will not extend into the path of a work sheet a that may overlap the right-hand end of the platen, as will be understood from a consideration of Figs. 3 and 4. Irojecting outwardly and horizontally from the foot piece 18 a considerable distance beyond the end plate 20, and beyond the right-hand end 15a of the carriage bed, and the correspond'- ing end of the paper apron 21 is abracket arm 22. vExtendin upwardly from the arm 22 is an arm 23 t at terminates before it reaches lines coincident with the cylindrical surface of the platen, in order not to form an obstruction for the overlapping end of a work sheet a, as indicated in Fig. 4. Bent to the right from the upper end of the arm 23 is a substantially horizontally arm 24 over which an overlapping end of lie, as shownin Fig. 4. Projecting upwardly from the outer end of the arm 24 is an upright arm 25 that extends to the pivotal axis of the platen 26 and is provided with a bearing 27 by which the platen is supported at one end thereof. A hollow cup-shaped linger piece or wheel, designated as a whole by the reference numeral 28, is preferably formed from metal as a shell having an outer disklike head 29 from the edge of'which extends a cylindrical flange 30 that projects towards the laten. The head 29 is formed with a tubu ar hub 31 that extends through and is supported in the bearing 27 on the supporting bracket. A. spindle 32 has its outer end disposed' Micaela seated in the hub 31 and is secured thereto by a .screw 33 threaded into a tapped opening in the hub and -extendin into a transverse opening 34 inthe spin e. Said spindle receives a bearing in a central opening in a platen head 35 secured by screws 36 to the wooden core 37 of the platen. The 'right-hand ortion of the spindle 32 has a longitudinally extendingspline groove 38 therein, and a spline projection 39 in the central bearing opening in the platen head extends into said groove. thus connected to turn with the platen but may receive an independent longitudinal movement therein. The outward longitudinal movement of the spindle ist limited by a pin 40 secured to the spindle and projecting into the spline groove 38. When the spindle is moved out to the Fig. 2 position, the pin 40 strikes the spline projection 39 and prevents a further outward movement of the spindle. I prefer to employ a sleeve 41 which surrounds the hub 31 and that part of the spindle 32 which projects outside of the platen. It will be seen that the righthand end of the sleeve bears against the bearing member 27 on the bracket, whereas the platen head 35 bears against the lefthand of the sleeve. The sleeve, therefore, receives thev end thrust of the platen to the right and holds it against movement in this direction. In order that access may be gained to the screw 33, I provide an 42 in one side of the sleeve 41 and which the screw may be introduced drawn.

The construction described enables the linger wheel to be moved from its expanded position for use shown in Figs. 2 and 4, and in dotted lines in Fi 1, to a compact position indicated in ful lines in Fig. 1. It will be seen that the construction and relation of the parts are such that when the finger wheel is in the wheel in the main is outside of or beyond the bracket arm 25 and the bearing member 27 carried thereby. It will be seen, moreover from an inspection of Fig. 1 that in this position the finger wheel extends into the path of the right-hand side 43 of the cover of the carrying case and prevents said case from being closed to enclose the machine therein. lVhen. however, the finger wheel 28 is moved from the expanded to the full line positionl in Fig. 1, said wheel telescopes over the bracket arms 24 and 25 and over the bearing 27; such parts at this time being received within the hollow wheel, and the wheel in the main will extend to the left of the bracket. arm 25. The step-shaped arrangement of the bracket arms 22, 23, 24 and 25 enables an efficient support to be provided for the platen atthis end thereof without interfering with the overlapping work sheet a extending' over the bracket arms 22, 23 and throu or wit The spindle is openinlg expanded position, saidv 24 to the inner face of the bracket arm 25 when the finger Wheel is in position for use. The construction also enables the finger wheel to receive a telescoping movement over the arms 24, 25 and the bearing 27, as described, so that. said parts may be received within the wheel and not interfere with its movement to compact position, thereby enabling the cover of the carrying case to be closed.

It will be seen that the diameter of the finger wheel 28 is greater than that. of the platen. and that when the Wheel is in the expanded position the inner edge 44 (see Figs. 3 and 4) of the Wheel will be in substantial alignment with or inside the inner face of the bracket arm 25, and in al position to act as a side edge gage for the work sheet o, to facilitate the introduction of the sheet into the machine and to indicate the limit to the right beyond which the operator cannot carry the sheet..

The left-hand end of the spindle 32 isl received and adapted to move longitudinally and to turn in a bearing member 45 in the left-hand end plate 46 of the carriage. in the usual manner. As is usual yin the, Ileniington Portable machine. and as is disclosed in the application of Joseph B. Holden. Sr. No. 547,128, filed March 27, i922. a member 47 is pivoted at 48 on the lefthand end plate of the carriage. This member 47 is provided with a` locking finger 49 that is received in a transverse slot 5() in the bearing member 45, and is adapted to extend across the bearing opening therein, as shown in Fig. 5. The member 47 is also provided with a depending locking member or projection 51 adapted to be received in a recess 52, see Fig. 1, of a spring locking latch 53 secured at one end to the carriage support 8. In the present instance this locking latch is secured to the carriage about, -125 of .an inch further to the left than ordinarily. The member 47 also has an arm 54 which carries a laterally bent finger piece 55 located in the rear of the carriage releasing arm 5G which terminates in a finger piece 57. This arm 56 is connected to a supporting plate 58 mounted on the carriage by pivots 59 and carrying a feed rack 60 which normally engages the lowermost feed dog 61 to restrain the power driven carriage against movement in the direction of its feed.

lt will be understood that the finger 49 normally extends into the path of the lefthand end of the spindle 32, as shown in Fig. 5, and prevents a longitudinal displacement' of the spindle to the left.. This prevents the finger Wheel from being moved to the left Where it. may clear the side wall 4? of the cover of the carrying case. Therefore in this condition the cover is prevented -from being closed, as hercinbefore pointed out.

In order to condition the machine for enclosure Within its carrying case, the operator, aside from contracting the type bars in the usual manner. presses forward on the finger piece 55 and then moves the finger wheel 28 to the left to the limit of its movement. The effect of actuating the finger piece 55 is to move the locking finger 4f) out of the path of the spindle 32. move the locking projection 51 down into effective position, and move the carriage releasing arm 56 forward, thereby releasing the feed rack to tree the carriage. While the parts are thus maintained by pressure exerted by the operator on the finger piece 55, the finger wheel 28 is moved to the full line Fig. 1 position. as explained. This thrusts the left-- hand end portion of the spindle 32 into the path of the finger 49 and p revents a return movement of the member 4t to normal position under the action of its spring 62. This results in locking the projection 51 in effective position and in locking the feed rack out of engagement with the normally engaged feed dog. T he carriage is then moved from its off centered position in either direction to a substantially centered position in its line of travel. When a substantially centered position is reached, the members 51 and 53 of the center lock automatically co-act to lock they carriage against travel in either direction from said centered position. With the machine thus conditioned. the cover may be closed and the machine enclosed Within its carrying case.

To re-condition the machine for use, it is merely necessary after removing the cover, to expand the type bars in the usual manner, and then move the finger Wheel 28 from the full to the dotted line position in' Fig. 1. The effect of this is to Withdraw the lefthand end portion of the spindle 32 out of the path of the locking finger 49. The spring 62 Will then return the member 47 to normal position shown in Fig. 5, thereby rendering the center lock ineffective and returning the carriage to the restraint of its escapement mechanism, by permitting the feed rack to return to normal position under the action of its springs 63.

While l prefer to employ the finger Wheel 28 in combination with the other features disclosed to control the center lock and carriage release. yet from certain aspects of my invention it is immaterial Whether the feed wheel be employed in such a combination.

It will be understood that in the specific construction as disclosed in the present instance. When a 9% inch'envelope or Work sheet a is in the machine and overlaps the right-hand end of the platen to the capacity of the, machine, as shown in Fig. 4, the finger Wheel is in position for use and extends outside of the supporting arm`25 and beyond the range of the envelope or work sheet, where the fin er wheel may be used effectively without interference from or interference with the envelope or work sheet.

Various changes may be made in the construction shown and described, and parts thereof may be employed without others without departing from my invention as it is defined in the accompanying claims.
